ELECTRIC CUNNEGIOR.

Specification of Letters Patent.

Application filed Qctoher 30, 1916. Serial No. 128,374.

To all whom it may concern:u

Be it known that I, FREDERICK J. OSIUS, a citizenof the United States and resident of Racine, in the county of Racine and. State of Wisconsin, have invented new and useful. Improvements in Electric Connectors, of which the following is a description, ref erence-being had to the accompanying; drawings, which are a part of this specification.

This invention relates to improvements in electrical connectors. In separable and other connectors the electric terminals are usually provided'with socketed portions in the form of binding posts for receiving the ends of the wires to which it is connected and the wires are clamped inposition by clamping screws threaded into the posts.

This manner of construction is ex ensive to manufacture end in use the bin ing screws tend to workand if clamped too tightly cut the loose wire. v

It 18 one of the ob3ects of the present 111- vention to overcome the beforementioned objectionable ieaturesand provide an electric connector in which the wires may be easily attached to the terminals of the con,-

nector without the liability of the wires accidentally becoming disconnected.

A further object. of the invention is to provide an electric connector which is of simple construction, is strong and durable and is well adapted for the purpose described.

With the above and other objects in View the invention consists of the improved electric cbnnector and'its parts and combinationsas set forth in theclaims and all equivalents thereof.

In the accompanying drawing in 'which the siame'refenence characters indicate the samefparts in all of the views:

Figure 1 is a side view of the improved; electric connector shown connected to elec-* tric circuit wires, a part of the being shown in section;

Fig. 2 is a transverse sectional .view taken on line 2-2 of Fig.1; 1

Fig. '3 is a longitudinal sectional view taken on line 3-3 of Fig. 2; and

connector Fig. 4.- is a' similar view takenon line.

/ of the same figure.

' Referring to. the drawing the numeral 8 indicates the casing of the improved connector which is formed of an insuletmg material and is divided medially of its length into two parts of which 9 is the pliig 01- tion. and 10 the receptacle portion. ach half portion of the casing consists of an outwardly extending threaded end 11. a tu- Patentd Dec; 2, 1919.

hular cap 12 threaded thereon and a. wire holding block 13 positioned within the cap and interposed between the cap and the threaded end of the casing.

The casing portions 9 and 10 are similar to each other and the plug portion '9 is provided with pxo jecting contact split spring pins 14 whic telescopingly enter the bores of the tubular contact pins 15 mounted in the receptacle portion 10 of the. casing. I These pins 14 and 15 of the respective casing portions also extend through said por tlons-end projectbeyon'd theends thereof "and into openings 16 providedjinthe holding blocks 13. The openings 16 'of ea'ch. parallel to the axis-thereoffaiid,

block extend diametrically opposite each other and corh -municate with the periphery of the blocks by slots 17 to provide for easily looping the end portions of the electric circuitwires 18 in the openings. The peripheral portionsof the blocks are also provided with clon gated locking slots 19 for receiving the bent over ends 18' of the wires 18.

The outer end portions "of the pins 14 and cated by the-numeral 14 and 15 to permit said ends to easily enter the opening 16 and to wedg'ingly clamp the wires 18 in position and form an electrical connection therewith.

In connecting the' half portions of the .15 are of poi'ntedor conical form as indicasingtothe circuit wires the parts are dis assembled and the wires are extended through the bore of the caps and then in sertcd laterally in the holding block open ings and the wire ends are thenbent over to form looped or hooked portions 20 and the end portions 18' thereof are then swung into the elongated locking; slots 19. The holding blocks are then pulled into the ca 8 by the wires until they beer aifiiinstt e shoulders 21 of said cap and the caps are then threaded on their respective case tions. When the parts are thus assem led:f-

the looped or hooked portions of thewire will be securely clamped between the hold ing blocks and the outer ends of the casing parts. The half parts c the casing are connected together as before described, by the entry of the split plug pins into the bores of the recess pins. I

From the foregoing description it will be to enter the recess, said Wire being clamped cap threaded. on the casing, and a holding member clamped between the casing andis Well, adapted for the purpose described.

What 1 claim as my invention is:

1. An electrical connector, coml'irising a casing having a connector pin projecting therefrom, a cap mounted on the casing and having an end opening, a Wire entering the cap opening and a holding block interposed between the casing and the cap and having an opening formed therein and into which opening the pin extends to form an electrical connection between the pin and the wire extending through both openings, said Wire being clamped between the holding block and the cap.

2. An electrical connector, comprising a casing having a connector pin projecting therefrom, a cap mounted on the casing, a wire extending through the cap and a holding block interposed between the casing and the cap and having an opening and a recess formed therein and into which opening the in extends to form an electrical conmotion between said pin and the Wire which extends through the opening and is bent between the l'iolding block and the cap.

3. An electrical connector, comprising a casing having a threaded portion and a projecting connector pin, a tubular removable the cap and having; an opening and a pcripheral recess, said opening being in communication Withthe peripheral portion of the holding member to permit a Wire to be inserted laterally therein and bent over one end of the member and the end of the wireto hers through which are in communication with rename be swung into the recess, the connector pin extending into the opening of the holding member to form an electrical connection with the wire.

An electrical connector, comprising a casing; having projecting connector pins, a tubular rcn'iovable cap threaded on the casint; and extending around the pins, wires extending through the cap and a holding member interposed between. the casing and the cap and having openings and recesses to permit the Wi'rcs to be extended through the openings and the ends of the wires to enter the recesses, the connector pins extending into the openings of the holding member to clamp the Wires therein and form electrical connections with the wires therein. l

5. An electrical connector, comprising a two-part casing each part of which having connector pins extending therethrough and projecting outwardl therefrom, the inner e-nd portionsot' the pins of one of said casing parts having av telescopic convection with the pins of the other casing part, caps removably mounted on the outereml portions of the casing parts, and holding members interposed between the caps and their respective casing parts, said holding memhaving openings extending therethe peripheral portions ofthe members and which receive the connector pins, said holding members also having peripheral recesses, the connector pins electrically engaging wires which extend through the openings of the holding members, said Wires also extending between the holding members and e the casing parts and entering the peripheral recesses.

.ln testnnoin. whereof, I afiix my signature.
